Claims. (Cl. 269-115) This invention relates to a tool used in securing together sheets of building material. With this tool, a nut is nonrotatably held in an ordinarily inaccessible position below aligned openings in two sheets of material so that the operator may easily secure a bolt to the nut to bind the sheets of material.

A primary object of the present invention is to provide a tool which holds one element of a fastener in proper position below aligned openings in sheets ofbuilding material.

A further object of the present invention is to provide a tool, used in securing together sheets of building material, which has positioning means thereon so that adjustment in only one direction is required to properly position the tool.

A further object of the present invention is to provide a tool for holding an element of a fastener below aligned openings in sheets of building material wherein the tool clamps on the work when in the proper position and is adaptable to carry a variety of fastening elements.

The invention will be more fully understood and further objects and advantages thereof will become apparent when reference is made to the following detailed de scription of a preferred embodiment of the invention and the accompanying drawings in which:

Fig. 1 is a pictorial view of the tool in position on a corrugated sheet of material;

Fig. 2 is a top plan View of the tool with a portion of the sheet showing; and

Fig. 3 is an elevation of the tool of Fig. 1.

Referring to the drawing there is shown a tool used in securing together sheets of corrugated material. The tool 10 comprises a base 12 on one end of which is secured a post 14 having a curved section 16 and a leg 18 extending parallel to the base 12. The base 12, post 14, and leg 18 may be formed of pipe sections, as shown in Fig. 3. On the other end of the base 12, there is secured a non-circular stud 20 for supporting a detachable adapter 22. A hollow nut holding socket 126 is secured on the stud 20 by a set screw 34 and a hollow washer holding socket 28 is secured on the socket 26 by the set'screw 44. A spring clip 54 in the socket 28 prevents the nut and washer from falling out of the adapter during manipulation of the tool.

The positioning means 68 comprises a rectangular arm 72 pivotally mounted on the post 14. The arm 72 has a pair of cars 74 that straddle the post 14 and on which a pair of vertical plates 78 are mounted. The pivot pin 76, about which the arm rotates, passes through the vertical plates 78 and the post 14. Formed in the lower surface of the arm 72 is a longitudinal recess 80 which receives the block 82. As shown in Fig. 3, the exposed surface 84 of the block 82 has a corrugated design. Bolts and nuts 86 secure the block 82 in the recess 80 to the arm 72.

A connecting link 88 is pivotally mounted on the upper surface of arm 72 by a hinge 90. An enlarged opening 92 in the link 88 allows for passage therethrough of the nited States Patent 9 ice leg 18. The link 88 and the arm 72 are urged toward the base 12 by a coil spring 94 connected to the link 88 by the screw 96. One end of the spring 94 is attached to the pivot pin 76 while the other end is secured to the leg 18 by the screw 98. Link 88 may be moved upwardly against the action of the spring 94 by the lever which is pivotally connected about an intermediate point to the leg 18 by pivot pin 102. At one end 103 the lever is pivotally connected to the link 88 by pivot pin 104.

The operation of the tool is illustrated in Fig. 1

wherein the tool 10 is shown in position on the free edge 70 of a sheet 60 of corrugated material. Corrugated sheets 60 and 64 are placed with their adjacent ends overlapping so that the openings 62 are aligned. A nut and a washer are placed in the sockets 26 and 28 of adapter 22 and are retained therein by the spring clip 54. Lever is depressed toward the leg 18 raising the link 88 and the arm 72 against the action of the spring 94. The tool is then placed on the corrugated sheet 60 so that the edge 76 is received between the arm 72 and the base 12. The pressure on the lever 100 is released so that the corrugations on the outer surface 84 of the block 82 are urged by the spring 94 to mate with the corrugations of sheet 60, thus positioning the adapter 22 the proper distance from the edge 70. Sufiicient pressure is then placed on the lever 100 to remove the positive clamping action between the arm 72 and the base 12 while retaining the corrugations 84 in the corrugations of the sheet 60, so that the tool 10 may be moved parallel to the corrugations. When the adapter 22 is in position below a pair of aligned openings 62, the pressure on the lever 100 is released allowing the arm 72 to move toward the base 12 clamping the tool 10 on the sheet 60. The bolt 66 is then passed through the openings 62 and the washer in the socket 28 and fastened to the nut held in the socket 26 to bind the corrugated'sheets 60 and 64.

The tool as described above has been found to be a great aid in assembling sheets of building material. It is to be appreciated that designs other than the corrugations illustrated may be placed on the block 82. In practice, the design on the block 82 will conform to the building material being used. Since the adapter 22 is easily removable from the stud 20, a variety of adapters are available to allow a wide choice of fasteners. As shown in Fig. 3, the base 12 is sufiiciently flexible so that the sheet 60 is not marred by the action of the tool.

Having thus described the invention in rather full detail, it will be understood that these details need not be strictly adhered to and that various changes in modifications may suggest themselves in one skilled in the art, all falling within the scope of the invention as defined by the subjoined claims.
